The main focus of the material presented by these guys pivots around identifying prior areas & zones of support & resistance that is used as landmarks or fulcrums as price weaves it’s way from point A to point B.
The primary objective is to recognize when price is exhibiting signs of developing a directional tone, calibrating the appropriate risk, getting seated & aiming for the next obvious zone/area of S&R, where the next decision will be made to pare out, add in or fully exit dependent upon the objective for the trade.
The technical description for supply or demand is hazy or cloudy at best, depending on where you read it & who is presenting it.
A strong imbalance (one or more bars/candles) at a particular level indicates the order book is weighted heavily in favor of one side, or there is a distinct lack of contrary orders.
The result of that top heavy imbalance would be a sharp & aggressive move away from a level & you would be seeking a repeat of the directional behavior next time it revisits, providing of course the imbalance still exists.
As opposed to price moving into a prior area of support/resistance, where if there exists a large build-up of contrary orders into a possible resistance zone for instance (offers tiered into & above the zone/limits/buy stops above the outer edge of resistance/trailing profit & sell stops leading into the zone) you would expect price to slow & consolidate whilst it absorbs the orders before the majority camp orchestrates the next leg (up or down).
Although each carry their own specific characteristics they can actually be traded in similar fashion if you’re looking to long/short out of the area via pullbacks.
As for plotting the relevant zones, there are multiple examples of this contained within all 3 threads. Just revisit the posts to see how they’re plotted.
Basically, S&R is identified as a zone as opposed to an exact line, which encompasses both wicks & bodies, signifying & illustrating an area where contrary price action was absorbed & prioritized according to the dominant bias.
Sometimes it will result in a sharp, aggressive pop out of the area, sometimes it will be a more sedate, slow trudge.
Like I said, it’s all there inside the thread(s) including the reasons for plotting them, the story leading into & out of the significant zones & even recommendations for managing the moves according to the individual traders objectives.
